- This version of Barbara Gordon, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
- Barbara Gordon was not named (except as "Mrs. Gordon") when she first appeared in 1951. Her name had to wait until her third appearance 30 years later.
